Identify the volume of a cone with base area 64π m2 and a height 4 m less than 3 times the radius, rounded to the nearest tenth.

d.The initial sales of 575 bicycles increases at the rate of 1.8% over t years.

Step-by-step explanation:

This equation is of the form

, where a represents the initial amount, r represents the percentage of growth or decay, n represents the number of times per year this growth or decay is compounded, and x represents the amount of time.

575 is in the place of a, so it is the initial value of sales.

0.018, or 1.8%, is in the place of r, so this is the percentage of growth.

4 is in the place of n, so it is the number of times per year the growth is compounded.

This means the initial sales of 575 increases at a rate of 1.8% over t years.
